Hello. I have a 16 year old son who was diagnosed with osteoporosis at age 14. They checked his bone density and said that his bones are not absorbing any vitamin d or e or calcium. They said that they will not do any more test to find out why because they probably will never find out why. He eats and drinks alot of things that are high in vitamin d and e and in calcium. He also takes vitamin pills everyday.

Why would a child his age develop this disease? What kind of test can find the reason why?

He has already crushed his number 1 verbrae and split his number 5. Broke his wrist twice and his foot once.

Hello,Thank you for writing in. Osteoporosis is rare in teenagers. I would recommend an evaluation by a pediatric endocrinologist as I suspect this is related to a metabolic bone disorder and should be further evaluated.

My differetial diagnosis would include:

Rare form of ricketsDiabetesMetabolic bone disorderGrowth hormone / short stature problemMalabsorbtion problem in the gutKidney disease (not able to metabolize the Vitamin D)Parathyroid disease

As you can see from some possible diagnosis that the cause can be complex and he should benefit from seeing an endocrinologist.
